    摘要： An ink composition contains particles having a solid coloring material substantially enclosed by a block polymer, and a solvent. The solid coloring material is enclosed in a micelle formed of the block polymer, and preferably 90 wt % or more of the solid coloring material are enclosed by the block polymer. The average particle size of the particles is 200 nm or less. A method for producing an ink composition includes forming the particles by insolubilizing the coloring material and the block polymer in a state of both being dissolved in a solution. The above described ink composition has an adequate dispersibility of the coloring material and is suitable for an ink composition for an ink-jet device.

    摘要： A polymer composition including a functional material, the composition containing at least a block polymer encapsulating a material of a predetermined function and a solvent, wherein a property of the polymer in the composition is changed in response to a stimulus, whereby the block polymer encapsulating the material agglomerates together, or an ink composition usable as an inkjet ink containing at least a block polymer encapsulating a coloring material and a solvent, wherein a property of the polymer in the composition is changed in response to a stimulus, whereby the block polymer encapsulating the coloring material agglomerates together. The change of the property of the block polymer in response to a stimulus is a change from the lyophilic nature to the lyophobic nature, or the lyophilic nature to the lyophobic nature.
